Preferences GUI allows user to configure Entertainer the easy way. Actually it's just a simple GUI for editing \texttt{/.entertainer/preferences.cfg} -configuration file and all the same things can be done with text editor directly. Regardless of this, it is still recommended to use GUI application, because it notifies the backend process that changes has been made. This way backend knows to reload configurations. If changes are made by hand with the text editor, then backend needs to be restarted to changes take effect. Preferences GUI is a standalone application and it can be used even if Entertainer is not running.
